Abstract

Wilayah pesisir Sawah Luhur menghadapi permasalahan serius terkait penumpukan limbah cangkang kerang yang berpotensi mencemari lingkungan dan menurunkan kualitas hidup masyarakat sekitar. Kondisi ini menunjukkan perlunya solusi inovatif yang tidak hanya mampu mengurangi dampak pencemaran, tetapi juga memberikan nilai tambah secara ekonomi. Topik pengabdian masyarakat ini dipilih karena limbah cangkang kerang memiliki potensi besar untuk diolah menjadi produk bernilai jual, sehingga mampu menciptakan sumber pendapatan alternatif bagi masyarakat pesisir sekaligus mendorong terwujudnya pembangunan berkelanjutan. Metode pelaksanaan kegiatan dilakukan melalui pendekatan community empowerment yang berbasis partisipasi aktif masyarakat. Tahapan pelaksanaan mencakup sosialisasi mengenai dampak limbah dan peluang pemanfaatannya, pelatihan teknis pengolahan cangkang kerang menjadi produk bernilai ekonomi seperti batako, pendampingan proses produksi, serta pembentukan kelompok usaha kecil berbasis komunitas. Dengan metode ini, masyarakat tidak hanya memperoleh keterampilan baru, tetapi juga didorong untuk berkolaborasi dalam mengembangkan usaha bersama. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan dan keterampilan masyarakat dalam mengelola limbah cangkang kerang, terbentuknya kelompok usaha mikro yang mampu menghasilkan produk bernilai tambah, serta berkurangnya pencemaran lingkungan pesisir akibat penumpukan limbah. Program ini membuktikan bahwa pemberdayaan masyarakat berbasis pengolahan limbah dapat memberikan manfaat ganda, yakni meningkatkan kesejahteraan ekonomi rumah tangga nelayan dan menjaga kelestarian lingkungan. Selanjutnya bertujuan meningkatkan kapasitas manajemen keuangan anggota UMKM Rumah Produksi Kerang Hijau melalui pelatihan dan penerapan sistem yang efektif. Hasil kuisioner menunjukkan terjadi peningkatan pemahaman, nilai  pre-test sebesar 52,7 sedangkan post-test meningkat menjadi 86,9.

Abstract

Problem solving ability is a student's capacity in solving questions or commonly called questions. Problem solving ability is an important component in solving student problems in answering questions given by the teacher. In this study, qualitative studies were analyzed on students' problem solving abilities at the elementary, junior high and high school levels between 1999 and 2022. Systematic Literature Review (SLR) which is a study methodology collects primary data that has been published in journals indexed by Sinta and Scopus . Collected 24 articles of data extraction results adjusted to the selection criteria. Qualitative methods were used in data analysis. Data are grouped according to year of publication, level of education, demography, journal indexer, study materials, and study findings. The research findings show that research on problem solving skills is a major trend in the field of social arithmetic from 1999 to 2022. Many studies on problem solving skills have been conducted at the elementary school level in the Java region. However, at all school levels, the ability to solve math problems is still very high. low . Finding the right solution is the most difficult part for students to master in the problem solving process. One of the factors is that students do not fully understand the material. This is a challenge for researchers and educators who conduct research on students' problem solving abilities, especially in fields where problems are rarely investigated.
